SE AMING-MACHINE.

Specification of Letters Patent.

Patented Nov. 26, 1907.

To all whom it may concern:

Be it known that I, OTTO S. BEYER, a citizen of the United States ofAmerica, and a resident of East Rutherford, county of Bergen, and Stateof New Jersey, have invented certain new and useful Improvements inSea'rning-ltiachines, of which the following is a specification.

My invention relates generally to seaming machines and has moreparticular reference to the gearing used in driving the different Iparts of the machine and to the combination of parts and features ofconstruction hereinafter set forth.

'Heretofore, it has been customary to have a plurality of seamingmembers mounted on the rotating seamer head so as to travel in an orbitaround the work to be acted upon, the said seaming members furtherhaving a movement toward and away from the work at the proper periods soas to properly engage with or act upon the seam to be formed. Inconnection with this, it has generally been customary to have, anautomatic feeding mechanism for the cans adapted to bring the said-canssuccessively into and out of position with regard to the chuck andseaming members, at the moment when the seaming members are in aposition to admit the passage of the cans. In some cases, however, it isdesirable to have a hand-fed machine and in order that the finished canmay be removed by the operator, it is necessary that the movement of theseaming members toward and away from the work should cease while thesaid can is removed and after it is finished. It is obvious that thisreplacing of the can must be substantially at the moment when theseaming members are in the position farthest away from the work. Theseaming members are therefore normally held awayfrom their operatingposition, and

are only actuated at will by the operator.

The seamer head, carrying the seaming member or members can, however,rotate continuously. In carrying out these objects, I provide the seamerhead with a pinion for each seaming member which travels around orrotates with the said seamer head and which furthermore has anindividual rotation around its own axis which acts to bring the seamingmembers into operating position. Means are provided for stoppmg theindividual rotation of these pinions at will and substantially at themoment when the seaming members are farthest away from the work. Theparts are so arranged that the said pinion or pinions makes onerevolution around its own axis to a certain predeter mined number ofrevolutions of the seamer head. In this instance, the relation is 1 to12, the pinion making one revolution around its own axis to 12revolutions of the seamer head. This proportion .can of course bechanged at will. To impart the necessary motion to this pinion orpinions, I provide a gear placed concentric with the seamer head andrunning at a speed slightly greater than the said seamer head, therelation being. in the present instance 12; of the said concentric gearto 12 revolutions of the "seamer head. This concentric gear is drivenfrom a train of gears which preferably connect with a gear mounted onthe spindle of the seamer head andrunning at the said speed of theseamer head. A clutch mechanism is interposed in the said train of gearssuitably con trolled to throw the clutch in substantially at the samemoment the can is clamped between the work supporter and the chuck. Inthe present instance, a treadle mechanism is used for this purpose.

A suitable locking means is used to maintain the parts in their workingosition after they have beernmoved into t 1e same, and means areprovided whereby the said locking means is unlatched or freedautomatically so as to disengage the clutch with its cooperatlng meansafter a certain predetermined pe riod. In the resent instance, the artsare so arranged t lat after the seamer ead has made 12 revolutions andthe pinion carried by the same has made one revolution around its ownaxis that the said clutch mechainsln' will be thrown out of engagementwith its operating mechanism.

The means for stopping the individual rotation of the pinion around itsown axis, consists in the present instance of a cam and a stop forpreventing the rotation of the said also part y in section.

' the seaming members.

stop, however, has the effect of preventing the backward rotation of thepinion, the result being that the gear placed concentric with the seamerhead and which is rotating at a speed slightly greater. than the saidseamer head will be carried around at the same speed as the seamer headwhen the seaming operation ceases. When the clutch is thrown in again,the stop, cooperating With the cam carried by the pinion, will bewithdrawn so as to allow the pinion to be rotated around its own axisand the diilerence in s eed between the scanner head and the gear p acedconcentric with the same being relatively very small, there is no jar orshock in starting or stopping the machine at any time. 1

In the drawings 1 have'embodied my invention in a useful and preferredform without, however, wishing to be understood as limiting myself inany way to the construction therein set forth.

In the said drawings: Figure 1 is aside elevation of the machineembodying my in vention, partly in section. Fig. 2 is a lan' view of theunder side of the chuck and seamer head showing three seaming membersused in the present instance. Fig. 3 is a detail view of the seamerhead, showing the cam and-stops for the pinion which actuates Fig. 4 isa sectional view on the line a:zc of Fig. 1. Fig. 5 is an enlargeddetail view, partly in section, of the seamer head and adjacentelements. Fig. 5 is a detail view of the seaming member having twoopposed conical deflecting rolls.

. Fig. 7 is a sectional detail view of the head and seaming membersshowing more particularly the means for moving the seeming memberstoward and away from the work. Fig. 8 is a detail view of one of theseaming members as 7 partly in section. Fig. 9 is another detail view ofthe seaming member 7 showing more particularly the means for moving theconical deflecting rolls toward and awe "from each other.

Similar characters of reference indicate corresponding parts in thedifferent views.

1 indicates a frameworkof any suitable construction for properlysupporting the various parts. p

2 indicates the seamer head which is suitably operated from the shaft 3through the instrumentality of the miter gears t and 5.

The seamer head carries one or more seaming members as the case may be,but, is in the present instance provided with three seaming members c, 7and 8 which include in part two opposed conical deflecting roll carriedby the member 7. These seaming members may of course be constructed inany suitable way and may be caused to move into and out of seamingposition in any suitable manner. Preferably, however. they contour ofthe said work.

This view is senses are provided with a contour carrier 96 pivoted onthe head 2 in the usual manner on the studs 12.

Mounted on the contour carrier is a seaming carrier 13 which in turncarries the seaming tools. This arrangement could of course be reversedand the contour carrier mounted on the seaming carrier, in whichinstance the seaming tools would be carried by the contour carrier, theonly requisite being that the seaming tqols partake o'r the motion ofboth carriers.

The contour carrier )0 will conveniently take the form of an arm havingan extension 91 carrying the roller 9 adapted to travel in the cam 10carried by the chuck 11. As the bers will be carried around with thesame and will be caused to travel in an orbit around i the work to beacted upon parallel to the g in the present instance, where the work issquare, the cam 10 will of course have a contour substantially identicalwith the contour of the can or work to be acted upon. The cam 10 is ofcourse stationary with the work to be acted upon. The seaming carrier.13 will conveniently take the form or' a bell crank lever and ispivoted at 14 on the contourcarrier 90. This seaming carrier carries theseaming tools which in the present instance are in the form of rolls,the second member having two opposed conical deflecting rolls. Anysuitable means can of course be provided for moving the seaming carriertoward and away from the work. In the present instance, it isconstructed as follows: One end of the lever or seaming carrier 13 isconnected with the plunger 92 sliding in the cylinder 93 in which islocated the spring 94 for yielding to any unevenness in theseam. Thistube is carried by a sliding member 95 provided with an ex 'ansionspring 96 which normally tends to lied the seaming member awayfrom thework. inside the contour carrier; is a spindle 97 carrying the pinion 16at its upper end and the cam 15 at its lower end. Carried by the slidingmember is a roller 98 with which the cam 15 is adapted to engage to movethe seaming carrier toward the work. This construction is common to allthree members. seaming member carries the crimping or curling roll 99,and the seaming carrier on the third seaming member carries thefinishing roll 100, while the second seaming member carries two opposedconical deflecting rolls 101 and 102 respectively. 1

The foregoing describes the construction of the first and thirdseaming-members. The second seaming member, however, must in addition tothe above means, he provided The seaming carrier on the first with amechanism for moving the conical deflecting rolls toward and away fromeach other at the proper moment.

svnsee Pivoted on the seaming carrier, 13 is a straddling link 103 whichcarries the lower deflecting roll 102. 104 indicates a stud also mountedon the seaming carrier carrying the lowerarm 105 adapted to engage withthe straddling link 103. .Mounted on the said stud 104 is an upper arm106 which bears upon a portion of the contour carrier 90. When theseaming carrier moves in toward the work, the arm 106 will engage withthe contour carrier 90 thereby causing the arm 165 to move thestraddling link 103 and the roll 102 in an upward direction so as tomove the said roll 102 up against the conical deflecting roll 101. Uponthe return movement of the seaming carrier, the reverse action it illtake place.

As there are three seaming members in the present instance, there willof course be three pinions, one for each seaniin member, but

revolution around its own axis'of the pinion,

the concentric gear making 12%; revolutions during the'same period toimpart this one revolution to the said pinion. It will of course beunderstood that if the concentric gear were drivenat the same speed asthe seamer head, the pinion would not rotate inasmuch as'the'said piniontravels in an orbit around with the seamer head and at the same speed asthe latter. The, said concentric gear 17 receives its motion in auitable way from a train of gears including the gears 18, 19, 20, and21. The gears 19 and 20 are mounted on a sedarate spindle 22, the gear19 being mounted fast and the gear 20 being mounted loose on the same.The gear 21 moves at the same speed as the seamer head and is mountedupon the spindle 24 which carries the said seamer head. A suitableclutch mechanism is interposed in the said train of gears consisting inthis case of the clutch 25 mounted on the spindle 22 and adapted toengage with the gear 20 to cause the motion of the said gear to beimparted to the spindle 22 and thence to the othergears.

26 is the work supporter adapted to receive the can.

27 indicates a treadle, the motion of which is imparted throu h the rod28 to the bell crank 29 connected to the loose collar 60 on the worksupporter by means of link 61. The work supporter further carries thefixed sleeve 62 between which and the loose sleeve is interposed thespring 63. The bell crank 29 carries an arm 64 which is attached to thelink '30 provided with the slot 65 at its free end in which plays thepin 66 of the bell crank 31. Mounted on this pin 66 is a latch 67provided with a hook 68 engaging the pin 69 on the link 30. This latchis further provided with a projection 70 having a slot 71 in which thepin 72, stationaryon the frame work engages. Connectin with the bellcrank 31 is a rod 32 exten in upward and mounted on the pin 73. carriedby the forked member 35. This member 35 is pivoted on the stud 74attached to'the bracket 75 on the framework, and is provided with twopro- .jections 76 and 77 betweeri which extends the arm 78 of the clutchlever 33 enga ing in the sleeve 34 of the clutch. This clutc lever 33 islikewise mounted loosely on the stud 74.

Mounted on the pivot 79 of the member 35 is a hook 36 which is adaptedto en age with the ledge 80 on the bracket 75 to dock the parts when thetreadle is depressed. A spring seated plun er 81 tends to push the lowerend of the hook 36 outward at all times. Mounted on the pivot 82 of thebracket 75 is a bell crank 43 adapted to move the sleeve 42 downward bymeans of the lever 44 pivoted on the bell crank 43 and resting on thetop of the hook 36. The pin ion 16 is provided with the cam 37 withwhich engages the stop 38 in the-notch 39 of the said cam after it hasmade one revolution around its own axis. This stop releases the cam andthereby the pinion by.

connections from the sleeve42 consisting of the rod 41 attached to thesaid sleeve 42 by means of the screws 84. Rod 41 engages at its lowerend a lever 40 which in turn engages with the stop 38. The back stop 45is also provided to engage with the notch 46 of the cam 37 to preventthe pinion from turning backwards as otherwise might be the case.

When itis desired to seam a can, the said can is placed upon the worksupporter and the treadl depressed, thereby lifting the work supporterand clamping the can. Throu h the instrumcntality of the link 30, therod 3 and lifting the hook 36 up on the ledge 80 at the same timethrowing the stop 38 out of en agement with the notch 39 of the cam 37.

wing to the construction of the link 30 with the slot 65, the can iscaused to be clamped sli htly in advance of the throwing in of thecTutch and the beginning of the seaming operation. The movement of thislink 30 causes the latch 67 to turnaround the pin 66 by reason of thepin 72 in the slot the member 35 pushes against the arm 78 of the clutchlever 34 moving the clutch in.

2 is lifted throwing the clutch 25 in en the rod is thus elevated, theprojection? 7 on &

As the member 35 swings around the pivot 74, the hook 36 is lifted upand the spring seated pin 81 normally pressing the lower end of the hookoutward, will cause the said hook to engage properly with the ledge 80on the bracket locking the parts. The projection 77 is provided with a'spring seated plunger 85 so as to take up any discrepancy in themovement of the parts between the clutch 25 and hook 36. The throwingout of the stop 38 releases the pinion 16 and the clutch 25 through thetrain of gears imparts to it an individual rotation around its own axiswhereby the seaming members successively move in toward the can. andscam the same. After the said pinion 16 has made one revolution, thestop 38 automatically acts through the lever 40, rod 41, sleeve 42, bellcrank 43, and lever 44, pushing the hook 36 off the ledge 80, thedownward movement of the parts connected thereto beingfacilitated bymeans of the spring seated plunger 86 on the bracket 75 acting against aportion of the member 35 so that the release is instantaneous. Themember 35 being thus turned around the pivot 74, the projection 76engages with the arm 78 throwing the clutch 25 out and pressing orpushing the rod 32 downward, thereby causing the work supporter to bereleased by reason of the latch 67 turnin around the pin 66 unhookingthe hook 68 from engagement with the pin 69 and allowing the link 30 tomove back.

The weight of the work su porter will generally be suificient to cause te return movement when released but the spring 63 also assists in movingit back or down. This release is accomplished substantially at themoment when the seaming members are farand in the same direction.

thest away from the work. The back stop prevents the rotation of thepinion in the opposite direction as it travels in an orbit around withthe seamer head and at the same speed with the same, and the concentricgear from which it receives its motion no longer being driven from itstrain of gears will rotate at the same speed as the seamer head Ifseveral seaming members are used, each of the said seaming members willbe provided with a pinion, but it is only necessary to have a cam, astop, and back stop on one of the said pinions.

The specific construction of the seaming members is not claimed in thisapplication, as it has been made the subject matter of otherapplications by me Ser. No. 186,602,
